what about a 350bhp coupe running on LPG. good performance and cheap to fill.

what do you guys think??

been done - got through three engines IIRC - search for user "Kingpleb" and read all about it

I have a feeling that a higher quality installation and some quality mapping may have prevented the failures, so don't dismiss it

ive heard that flash tube is a must to prevent damaging the valve seats?

im trying to think of ways to keep the coupe and performance instead of going TDI

Kingpleb! Legend... Gt28rs on it too!

interesting read.

alot of money spent, that was in 2007 though, maybe 6 years on there should be more safe multi point systems around.

seen a few M3 and S4 fans saying it was a good idea and no problems after conversion.

I wouldn't be too concerned about getting the extra power. An LPG car is a faster car from A to B because you aren't worrying about fuel consumption.

My LPG Rover did 225000 miles before the valve seats needed doing. I don't know how much cost / hassle is involved in Flashlube, but I'd be inclined to live with the additional wear unless Flashlube was really cheap and easy.

I think the flash lube is £250 max, I think I would have it for extra safety.

Don't do it.
You use more LPG to fuel also the conversion MPG isn't much off petrol.
Fuel also cools whereas LPG is effectively a gas and dramatically increases both egt's and cylinder temperatures .
The initial investment will also take around 30k miles before you see any benefit.
If fuel prices are a concern then buy a diesel and use coupe at weekends.

i had an lpg vectra estate in 2007, that was rapid but i spent loads of time trying to find garages that sold it bk then, but i never had a problem with the system.

I know you get less mpg than petrol, but it's cheaper.
250 miles off a £25/30 tank?

Yes you prob have to fill up a little more often, as I'll put a doughnut tank in the spare wheel well.

£1800 approx fitted. And then filling up £25 a time instead of £60 a time. Looking like a no brainer for doing rep miles and wanting to keep a unique and powerful car.

Might this be your reasonable solution?

Lol, that's been for sale for a while. If I could get 250-300bhp out if it then maybe. Horrid engine bay.
